How to setup Consent Mode for Google Tag (gtag.js) with UniConsent

About Google Consent Mode CMP →

The Google tag is a single tag you can add to your website to use Google measurement and advertising products like Google Ads, Google Analytics, Campaign Manager, Display & Video 360, and Search Ads 360. Instead of managing multiple tags for different Google products, you can use the Google tag across your entire site and connect the tag to multiple destinations.

How Google tag (gtag.js) looks like?

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=TAG_ID"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());

gtag('config', 'TAG_ID');
</script>

You can find your Google tag ID within Google Ads, Google Analytics and Google Tag Manager.

Example of Google tag (gtag.js) and UniConsent Setup

Basic Consent Mode

Put the following tag just before UniConsent CMP tag and before your Google tags or any other advertising tags:

<script>
(function() {
    if(!window['gtag']) {
        window['dataLayer'] = window['dataLayer'] || [];
        window['gtag'] = function(){window['dataLayer'].push(arguments);}
    }
    window['gtag']('set', 'developer_id.dZTcxZD', true);
    window['gtag']('consent', 'default', {
        ad_storage: 'denied',
        functionality_storage: 'denied',
        personalization_storage: 'denied',
        analytics_storage: 'denied',
        ad_user_data: 'denied',
        ad_personalization: 'denied',
        security_storage: 'granted',
        wait_for_update: 1000
    });
    window['gtag']("set", "ads_data_redaction", true);
    window['gtag']("set", "url_passthrough", false);
})();
</script>
<!-- // or use gcm short tag
<script src="https://cmp.uniconsent.com/v2/stubgcm.min.js"></script>
-->
<script src="https://cmp.uniconsent.com/v2/stub.min.js"></script>
<script async src='https://cmp.uniconsent.com/v2/YOUR-LICENSE-ID/cmp.js'></script>

<!-- // only load gtag once consent is collected -->
<!-- Google tag (gtag.js) -->
<script type="text/unicscript" unic-gcm-ids="analytics_storage,ad_user_data" src="https://www.googletagmanager.com/gtag/js?id=TAG_ID"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}

  gtag('js', new Date());
  gtag('config', 'TAG_ID');

</script>

The above codes delay all the Google tag cookies until the user grants consent.

Advanced Consent Mode (Google Consent Mode V2)

Put the following tag just before UniConsent CMP tag and before your Google tags (gtag.js) or any other advertising tags:

<script>
(function() {
    if(!window['gtag']) {
        window['dataLayer'] = window['dataLayer'] || [];
        window['gtag'] = function(){window['dataLayer'].push(arguments);}
    }
    window['gtag']('set', 'developer_id.dZTcxZD', true);
    window['gtag']('consent', 'default', {
        ad_storage: 'denied',
        functionality_storage: 'denied',
        personalization_storage: 'denied',
        analytics_storage: 'denied',
        ad_user_data: 'denied',
        ad_personalization: 'denied',
        security_storage: 'granted',
        wait_for_update: 1000
    });
    window['gtag']("set", "ads_data_redaction", true);
    window['gtag']("set", "url_passthrough", false);
})();
</script>
<!-- // or use gcm short tag
<script src="https://cmp.uniconsent.com/v2/stubgcm.min.js"></script>
-->
<script src="https://cmp.uniconsent.com/v2/stub.min.js"></script>
<script async src='https://cmp.uniconsent.com/v2/YOUR-LICENSE-ID/cmp.js'></script>

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=TAG_ID">
</script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}

  gtag('js', new Date());
  gtag('config', 'TAG_ID');

</script>

The above codes communicate with Google services via Consent Mode V2 api. Find more about Google Consent Mode V2
